| The Sound Barrier - Peace and quiet come naturally
with these patio doors. A hallmark of quality living for over 25 years, they're still
regarded today as one of the world's most innovative and popular patio door systems.
You'll get the ultimate in thermal performance and sound abatement. Multi-chamber
profiles, triple weather stripping at side stiles and triple-contact weather stripping at
meeting stiles virtually eliminate outside noise. You'll also enjoy peace of mind with our
superior locking system that lets you sleep secure, knowing your doors will stay closed.
And since PVC resists the effects of weather, our patio door is virtually
maintenance-free— it will not rot, rust, pit or blister. Available in 2-panel,
3-panel and 4-panel configurations, with 5 standard widths and 3 standard heights.  The
Door For All Seasons
PVC doors are built to perform in the
toughest conditions. At P.H. Tech, we test our doors against the most stringent industry
standards for air and water infiltration, wind-load resistance, ease of operation, forced
entry and much more. Which means you'll have lower heating and air-conditioning costs,
easier cleaning and low-cost maintenance, in addition to increased comfort— total
performance satisfaction year round, for years and years to come.
